How to Start a Skylight Installation Business

How do you start a skylight installation business from scratch?

Learn flashing on real roofs first, then register the business, bind general liability, check your state and city license rules, open a VELUX supplier account, and sub your first replacements for a roofer.

The skill gate here is flashing, not carpentry. Anyone can cut a hole in a roof. Only a trained installer gets the apron, step and head flashing layered bottom to top so every piece sheds onto the one below it. Get that time on real roofs before you sell your first job.

• Get real roof time first. Work for a roofing company or a skylight specialist until you can flash a deck-mount unit without stopping to think about the order.
• Register the LLC and bind general liability before you quote anything. A standard $1 million per occurrence, $2 million aggregate policy runs $77 to $139 a month, and homeowners will ask for the certificate.
• Check your state contractor board and your local building department. Roofing rules change by state, by city and by county, so verify both before you sell work.
• Pick your lane. Like-for-like replacements and sun tunnels are the fastest money because the opening already exists and the job runs 3 to 5 hours.
• Open a supplier account and learn the flashing kits cold: EDL for deck-mount on shingle, EDW for tile and high-profile, ECL for curb-mount. The factory kit is what carries the VELUX 10 year No Leak installation warranty.
• Learn to order by model code so you do not eat a restock fee. FS is fixed deck-mount, VS, VSE and VSS are vented manual, electric and solar, and the FCM and VCM families are curb-mount.
• Get your first job from a roofing company that hates skylight work. Most of them do, and they will hand you the calls rather than eat the callback risk.

What does it cost to start a skylight installation business?

Added straight down, a lean solo start is $19,568 to $57,152 and the truck is most of it. A fully equipped crew with new vans, marketing and working capital runs $100,000 to $250,000.

The vehicle is the swing item. A used work truck at $15,000 to $45,000 does the same job as a new 2026 Ford Transit 250, which stickers at $51,795 and actually transacts near $47,640, and the used truck is what keeps your first year cash alive. Strip out the truck and trailer and everything else on the list, tools, license, and a full year of both insurances, comes to $4,568 to $9,152. Published roofing startup guides quote a lean solo open at $15,000 to $35,000, which assumes you already own the truck or buy at the very bottom of that range.

Workers comp is the other swing item, and it is why the second man usually waits. NCCI class code 5551 for roofing runs $15 to $40 per $100 of payroll in the voluntary market and past $80 in some assigned-risk states, the highest rated construction class in most of the country.

What licenses, certifications and insurance do you need?

Rules vary by state and city. Florida, Louisiana and Nevada issue roofing licenses. California uses the C-39 classification. Texas, Colorado and Indiana have no state license. Carry general liability everywhere.

There is no skylight license anywhere in the country. You are licensed as a roofer or you are not licensed at all, and the local building department still pulls the permit either way. Verify with the state contractor board and the city permit office before you quote, because a city license can exist where a state license does not.

Permits are a real line item, not paperwork. Expect $50 to $400 for the permit and another $100 to $250 when an inspection is required. If the cut touches a truss or changes a load path, a structural engineer adds $300 to $800 and that goes in the quote, not in your margin.

• General liability: $77 to $139 a month for a standard $1 million per occurrence, $2 million aggregate policy. The roofing average sits near $252 a month, and California is the most expensive state in the country.
• Workers comp under class code 5551: roughly $15 to $40 per $100 of payroll, past $80 in some assigned-risk states. This is the number that keeps most skylight installers solo.
• License bond premium: 1 to 5 percent of the bond amount a year depending on credit, so $150 to $750 on a $15,000 bond. California's C-39 requires a $25,000 bond.
• NRCA ProCertification has no skylight track. The Asphalt Shingle installer path is the closest credential, at a $799 application plus a separate fee from the assessor for the hands-on performance exam.
• VELUX Skylight Specialist: 5 years in construction, licensed and insured, a 2 year installation warranty you write yourself, and factory training. VELUX says only about 10 percent of contractors are certified.
• Miami-Dade and Broward sit in the High-Velocity Hurricane Zone, so units need a Miami-Dade Notice of Acceptance and must pass TAS 201 large-missile impact, TAS 202 and TAS 203. Elsewhere in Florida you still need a Florida Product Approval.

What should you charge for skylight installation?

The national average install runs $1,911, with most jobs from $1,012 to $2,810. A like-for-like replacement fetches $800 to $2,400. Repairs run $75 for a reseal to $800 for a traced leak.

Price the job, not the hour, but know your hour. Roofing contractors bill $70 to $100 an hour, or $500 to $1,000 for a two-person crew day. Skylight repair labor sits lower at $30 to $80 an hour, so put a $150 to $300 call-out minimum on every repair or the drive eats the ticket.

Take a like-for-like replacement in Sacramento. You quote $2,400. The fixed deck-mount unit costs $520, the VELUX EDL C06 flashing kit is $119, ice and water shield plus shingles and sealant run about $80, and the permit is $150. That is $869 in hard cost. Your helper for the five hour job costs $200 loaded, and you pay yourself $450 for the day, which leaves $881 of gross profit, or 37 percent. That sits just above the 30 to 33 percent residential roofing crews actually run.

Never price a curb-mount job like a deck-mount job. Under a 3:12 pitch, IRC R308.6.8 requires the unit to sit on a curb not less than 4 inches above the plane of the roof unless the manufacturer's instructions say otherwise, which means framing and waterproofing that curb before the unit ever goes on. That is easily another two hours and it belongs in the quote.

How do you get your first skylight customers?

Go where old skylights already sit. Knock subdivisions built twenty to twenty-five years ago, get on roofing company subcontractor lists, claim your Google Business Profile, and call leak calls back first.

Skylights fail on a clock. Acrylic domes last 15 to 20 years and glass units 20 to 30, and past the 20 year mark replacement usually beats repair because seals, gaskets, flashing and frame are all aging at once. That means your territory is any subdivision built in the early 2000s, and you can spot the candidates from the street.

Say you spend $300 printing 2,000 door hangers and walk them through one of those subdivisions yourself. Two homeowners call and one books. At the $1,911 average, that job carries about $630 of gross profit at a 33 percent margin, so the drop pays for itself twice over on the first booking. The caller who does not book this spring often phones back in the fall, the first time a rain shows up on the ceiling.

• Call every roofing company within 30 miles and offer to sub the skylight portion. Roofers hate light shaft work and callback risk, so this is the fastest pipeline you have.
• Fill your Google Business Profile with photos of step flashing woven into the courses, not finished ceilings. Homeowners searching after a leak are shopping for competence.
• Answer the phone. Leak calls are emergencies and the second contractor to call back almost never gets the job.
• Photograph the flashing sequence on every job and text it to the customer. Those photos are your proof on a callback and your ads afterward.
• Ask for the review before you pack the ladder, standing in the room with the new light coming through it.
• Work home inspectors and property managers. They write up fogged glass and stained light shafts constantly and have nobody to refer them to.

What tools and equipment does a skylight installer need?

A coil roofing nailer, circular saw, reciprocating saw, 22 ft ladder, harness and lifeline, roof anchor and tin snips run $1,500 to $3,500. A full launch kit with compressor and staging reaches $15,000.

Buy the fall protection before the power tools. Cut the deck with a circular saw set just past the sheathing thickness so you do not chew into a rafter, and keep the recip saw for the framing and the old nails. On commercial roofs, OSHA 1926.501(b)(4) requires every skylight opening to be covered by something rated for at least twice the weight of the workers, equipment and material on it, secured and marked HOLE or COVER.

What should you do in the first 90 days?

Weeks one and two, bind liability and open a supplier account. Weeks three to six, sub for roofers and install your first replacements. Weeks seven to twelve, turn job photos into reviews.

What mistakes kill new skylight installation businesses?

Reusing old flashing, layering the head flashing wrong, skipping ice and water shield, leaving the light shaft uninsulated, and skipping permits. Almost every skylight leak traces back to installer error.

One callback can erase the profit on three jobs. Roofing pros estimate about 99 percent of skylight leaks come from human error rather than product failure, and only about half of reported leaks are coming from the unit at all. The rest is condensation, which the customer will still call a leak.

• Reusing old flashing or substituting a generic kit. It leaks, and it voids the VELUX 10 year No Leak installation warranty, which is only in force with the factory flashing kit.
• Setting the head or saddle flashing over the shingles above it instead of under. That reverses the water path and the roof drains into the house.
• Trusting sealant instead of mechanical flashing. Sealant is a backup, never the water plane.
• Skipping the ice and water shield around the opening to save 20 minutes and a few dollars of membrane.
• Using aluminum flashing thinner than 0.019 in., or plastic components that break down from UV within 5 to 7 years.
• Nailing through the flashing where the fastener sits in the water plane instead of high on the downhill edge, under the course above.
• Leaving the light shaft uninsulated with no vapor barrier. The customer calls every cold week all winter about a leak that is condensation.
• Setting a deck-mount unit on a roof under 3:12 instead of building the required 4 inch curb.
• Skipping the permit. Cutting structural framing almost always needs one, and a failed inspection can cost you the job and the license.

Is a skylight installation business worth it?

Yes, if you sell volume. Gross margins run 25 to 40 percent and net lands near 5 to 15 percent. Owners under one million in revenue take home $70,000 to $150,000.

Run the volume math before you quit anything. A solo installer who books two jobs a week for forty working weeks does eighty jobs. At a $1,700 average, below the $1,911 national number because replacements price lower, that is $136,000 in revenue, and a 32 percent gross margin leaves $43,520 before insurance, truck and fuel. That is a real first year, not a great one, and it is why almost nobody stays skylight-only.

The ceiling problem is ticket size. A one-truck residential roofer hits $400,000 to $750,000 on 25 to 40 jobs a year because the average roof ticket is $12,000 to $18,000. At a $1,911 skylight ticket, the same $400,000 takes roughly 210 jobs. The shops that clear that number bundle roof work, shaft framing and drywall finish onto the skylight, or they run two crews.

The market itself is steady rather than exploding. US skylights were a $2.1 billion market in 2024 and are projected to reach $3.2 billion by 2033, a 4.8 percent annual growth rate. That is enough demand to build on and not enough to attract a national franchise, which is the gap a local specialist lives in.

• A two-person crew realistically completes 1 to 2 replacements a day, since a replacement takes 3 to 5 hours with the opening already there.
• Sun tunnels install faster and sell at $500 to $1,000, so they fill the gaps between larger jobs.
• Commercial work carries higher gross margin, around 35 to 40 percent, versus 30 to 33 percent on residential replacement.
• Net margin is thin across the whole trade. Most roofing companies net 5 to 10 percent, and well-run ones reach 12 to 15 percent.

When is skylight season and how do you fill the slow months?

Spring and fall are peak, with April through early June the best install window. Winter is slow for installs, so sell condensation diagnosis, shaft insulation and leak repair instead.

Sealants and flashing want temperatures around 50 to 70 degrees to cure right, which is why the calendar governs this trade more than most. Homeowners start searching in early spring and the spring slots fill first. Fall is the underrated season, because many customers defer to spring and you get less competition and easier scheduling.

How do you compete with VELUX specialists and Solatube dealers?

There is no national skylight franchise, so your rivals are roofers and dealer networks. Solatube dealers charge $1,206 to $1,423 per tube. Generic solar tubes installed run $600 to $1,100.

The branded systems carry a real premium and you can compete on either side of it. A generic solar tube installs at $600 to $1,100 while a Solatube Premier Dealer unit with up to 8 ft of tubing runs $1,206 to $1,423, roughly double. Sell the cheaper option on price and the branded option on warranty, but never pretend they are the same product.

• Certification is a moat you can cross. VELUX says only about 10 percent of contractors are certified, and the Skylight Specialist path needs 5 years in construction plus a 2 year installation warranty from you.
• The VELUX warranty is a sales tool: 10 years on installation, 20 years on the glass seal, 10 years on the product, 5 years on blinds and controls, and it only applies with the factory flashing kit.
• Solatube Premier Dealer is a dealer network with no entry fees, not a franchise, so joining costs you training time rather than a franchise fee.
• Do not repeat old tax credit marketing. The Section 25C credit that covered skylights at a $600 annual cap ended for property placed in service after December 31, 2025.
• Your local edge is speed. Dealer networks book out. If you can be on a leaking roof in 48 hours, you win jobs on response time alone.
